IMPROVEMENT IN WASHING-MACHINE.

The Schedule referred vto in these Letters Patent and making part ofthe same.

To all 'whom fit mayv concern: l s

Be it known that I, WILLIAM T. MCKEAN, of East Palestine, in the county of Columbiana, and in the State of Ohio,vhave invented certain new and useful Improvements in WVashing-Machines; and do hereby declare thatthe following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, making a part of this specification, in which- Figure l is a plan view ofthe upper side of my improved device, and

Figure 2 is a vertical central section of the same.

Letters of like name and kind refer to like parts in each of the figures.

My invention belongs to, a class of devices having for their object the cleansin'gof soiled clothing by mechanical means; and

It consists in the peculiar construction and arrangement of the various parts of the device, as is hereinafter fully described.

In the annexed drawing- A represents a rectangular-shaped trough or box, the bottom of which slopes downward from the ends to the centre, so as,t0 give increased depth at that point.

Four legs, B, of suitable height, are secured to the corners of, and furnish a supportfor said trough.

J ournaled within suitable boxes, E, resting wit-hin the sides of the trough, is a metal shaft, I), having secured thereto a uted wooden cylinder, C, which may be rotated, together with said shaft, by means of a crank, F, lattached to one end of the same outside of the trough.

G G represent two bars, connected together at their outer' ends by means of a cross-bar, G', and pivoted at their inner ends, H, to the inner ends of two short bars, G", which, in turn,-are connected together at their outer ends, by means of a cross-bar, G, the whole forming a frame for containing a series of small rollers, N, suitably-journaled within said sidebars G, with their axes parallel with that of the luted cylinder C, the journalsof the central roller N forming the pivot for connecting together the sections of the Ii'ame.

As seen in iig. 2, the upper edges of the side-bars G are straight, while their lower edges present the form of an obtuse angle, the vertex of which, K, is placed ata distance from the pivot H corresponding with the length of the bars G.

Immediately above said vertex K; is a rod, M, which, passing through the bars G, has its projecting ends journalled within the lower ends of corresponding vertical grooves, a, cut within the inner faces of the sideboards of the trough, the ends of said rod thus forming fulcrum-pivots, upon which the frame rests, and is permitted to oscillate, so that by depressing or raising its outer end, ,a corresponding opposite motion of the central or .jointed portion of the same yis produced.

A suitable Weight, L, being suspended from the outer end of the roller-frame, the device is complete, and is operated as follows:

A suitable quantity of suds being supplied to the trough, the clothing to be washed is placed therein, and `the cylinder' C revolved, so as to cause said clothing to pass back and forth between it and the small rollers N, by which means all dirt will be easily and quickly removed from the-fabrics, Without, in the slightest degree, injuring the same.

The flexibility of the roller-frame, together' with the operation thereonv of the weight, renders the pressure between the cylinder and rollers uniform at all times, regardless of the thickness of the clothing lbeing operated upon, which pressure maybe varied at will, by increasing or diminishing the weight.

Having thus fully set forth the nature and merits ot' my invention,

What I claim as new, and desire tsecure by Letv ters Patent, is In a washing-machine, a roller-frame, jointed at its centre, longitudinally, and resting upon fulcrum-pivots, so that the weight, attached to one end of said frame, shall press the jointed central portion against a rotating cylinder', as shown, and for the purpose herein specified.

Also, the hereimdescribed washing-machine, consisting of the box or trough A, the legs B, the flut-ed cylinder C, the shaft D, the boxes E, the crank F, the centre-jointed frame G, G, G,and G, the weightL, the

fulcruIn-pivots M, and the rollers N, all constructed and arranged as and for the purpose specied.

In testimony that I claim the foregoing, I have hereunto set my hand, this 8th day of May, 1868.

. WM. T. MCKEAN.
